# $FreeBSD$

# Setup variables for the compiler
#
# COMPILER_TYPE is the major type of compiler. Currently gcc and clang support
# automatic detection. Other compiler types can be shoe-horned in, but require
# explicit setting of the compiler type. The compiler type can also be set
# explicitly if, say, you install gcc as clang...
#
# COMPILER_VERSION is a numeric constant equal to:
#     major * 10000 + minor * 100 + tiny
# It too can be overridden on the command line. When testing it, be sure to
# make sure that you are limiting the test to a specific compiler. Testing
# against 30300 for gcc likely isn't  what you wanted (since versions of gcc
# prior to 4.2 likely have no prayer of working).
#
# COMPILER_FREEBSD_VERSION is the compiler's __FreeBSD_cc_version value.
#
# COMPILER_FEATURES will contain one or more of the following, based on
# compiler support for that feature:
#
# - c++17:     supports full (or nearly full) C++17 programming environment.
# - c++14:     supports full (or nearly full) C++14 programming environment.
# - c++11:     supports full (or nearly full) C++11 programming environment.
# - retpoline: supports the retpoline speculative execution vulnerability
#              mitigation.
# - init-all:  supports stack variable initialization.
#
# These variables with an X_ prefix will also be provided if XCC is set.
#
# This file may be included multiple times, but only has effect the first time.
